ANET (Arista Networks) stock split history

If you are searching for when did anet stock split, this article provides a clear, sourced timeline and explains the mechanics, investor implications, and how to track split-adjusted shares. You will find exact dates for each split, how the company implemented them, what shareholders needed to do (if anything), and practical guidance for tracking adjusted historical prices.

As of Dec 4, 2024, according to Arista Networks press release, the company completed a four-for-one stock split. As of Nov 18, 2021, Arista previously completed a four-for-one split. This article references Arista investor materials and contemporaneous market coverage to explain both actions.

Overview

For readers who want the short answer to when did anet stock split: Arista Networks (ticker ANET) completed two recent four-for-one stock splits — one effective on November 18, 2021, and a second with charter amendment effective at 4:30 p.m. EST on December 3, 2024 and trading on a split-adjusted basis beginning at the market open on December 4, 2024. The combined effect of those two 4-for-1 splits is a cumulative 16-for-1 increase in shares outstanding (a 16:1 cumulative ratio). Stock splits change the number of shares and the per-share price but do not, by themselves, change the company’s market capitalization.

If you specifically asked when did anet stock split because you need to adjust historical prices or share counts, note that historical price series and per-share metrics are commonly adjusted by data providers to reflect the cumulative 16:1 factor.

Company background

Arista Networks (NYSE: ANET) is a technology company focused on cloud and data-center networking products and software. Founded to provide high-performance network switching and routing solutions, the company grew through product innovation and enterprise adoption. Public companies often use stock splits to reduce the per-share trading price and increase accessibility for retail investors, to enhance trading liquidity, or to align share denominations with investor expectations. A stock split is typically a mechanically neutral corporate action that preserves each shareholder’s percentage ownership while increasing the number of outstanding shares.

2021 4-for-1 stock split (summary)

If you search when did anet stock split with respect to 2021, the answer is the company executed a four-for-one stock split that was reflected on November 18, 2021. In that action, shareholders received three additional shares for each share they held immediately before the split, resulting in four shares for each previous share.

Key points for the 2021 split:

Ratio: 4-for-1 (each pre-split share converted into four post-split shares).
Effective date: November 18, 2021 (market records and split-history pages list the ex/split date as November 18, 2021).
Immediate effect: Per-share market price adjusted downward by dividing by four; shares outstanding increased fourfold. Total market value of a holder’s investment remained the same immediately after the split (absent market moves).
Purpose: The company's public communications indicated the split was to make the stock more accessible and to support liquidity for a wider base of investors.

No action was required by most shareholders—registered holders received direct-account statements reflecting the new share counts, and brokerage accounts were adjusted automatically.

2024 4-for-1 stock split (detailed)

For readers asking when did anet stock split in its most recent action, Arista announced the second four-for-one split in November 2024 and completed the implementation in early December 2024. The following summarizes the official investor materials and implementation mechanics.

Announcement date: Nov 7, 2024 — the Arista Board of Directors declared a four-for-one forward stock split. This was stated in the company’s investor announcement and related investor FAQ.
Charter amendment effective: Dec 3, 2024 at 4:30 p.m. EST — Arista filed and effected an amendment to its certificate of incorporation to increase the authorized shares consistent with the 4:1 split.
Trading on split-adjusted basis: Dec 4, 2024 (market open) — shares began trading on exchanges on a split-adjusted basis on the morning of Dec 4, 2024.
Ratio and allocation: Four-for-one forward split — shareholders of record received three additional shares for every one share held immediately before the ex-split effective time.
Stated rationale: Per Arista’s investor materials and FAQ, the company’s stated reason for the split was to make shares more accessible to a broader base of investors and to support liquidity. The investor FAQ noted that the split was not intended to alter the economics of ownership or voting control.

As of Dec 4, 2024, according to Arista Networks press release and the company’s investor FAQ, the split was completed and broker and transfer-agent records were adjusted to reflect the new per‑share basis and share counts.

Implementation mechanics and shareholder process

Investors often ask how a stock split is implemented in practice. If you have been asking when did anet stock split and what you needed to do, the short answer is that no action was required by most shareholders. Below is how Arista implemented the 2024 split and how similar splits are commonly processed.

Corporate action via charter amendment: The board approved the split and filed an amendment to increase the number of authorized shares in the certificate of incorporation. For the 2024 split, that amendment became effective at 4:30 p.m. EST on Dec 3, 2024.
Record-keeping and Direct Registration System (DRS): Registered holders on the company’s books received communications and, where applicable, updated Direct Registration System statements. Arista’s investor FAQ explained the statements shareholders should expect.
Broker and transfer-agent adjustments: Brokerage accounts typically reflect split-adjusted share counts automatically. Custodial and omnibus accounts were adjusted by brokers; retail holders that hold directly in their name observed updates from the transfer agent.
Trading adjustments: Stock exchanges and market data providers adjusted trading records so that the share price and per-share metrics displayed on Dec 4, 2024 reflected the split. Trading volume and price prior to the ex-date are adjusted in historical data to keep time-series consistency.
No action required: Per Arista’s investor FAQ, shareholders did not need to take steps to receive additional shares or to effect the split allocation. If you hold shares in certificate form or have unusual account arrangements, consult the transfer agent communications.

If you use custodial trading platforms or a brokerage, your account should reflect the additional shares automatically after the split effective time.

Tax, ownership and voting effects

A common question when did anet stock split relates to taxes and ownership. Based on the company’s investor FAQ and standard U.S. tax practice for forward stock splits:

Tax treatment: Arista stated the split was intended to be a tax-free recapitalization for U.S. federal income tax purposes. That usually means the split does not trigger recognition of income for U.S. taxpayers; rather, the tax basis per share is adjusted downward proportionally while the total basis remains the same. Shareholders should consult their tax advisors for individual circumstances.
Ownership percentage: The split did not change any shareholder’s percentage ownership of Arista (absent concurrent share issuances or buybacks). Each shareholder’s proportional stake remained the same because additional shares were allocated pro rata to existing holders.
Voting power: Because the split simply increased the number of ordinary shares outstanding on a proportional basis, it did not alter a shareholder’s relative voting power.

Note: Tax rules can vary by jurisdiction and individual circumstances. If you are a non-U.S. person or have specialized tax situations, consult a qualified tax advisor before concluding on tax effects.

Market reaction and short-term price impact

Readers searching when did anet stock split sometimes expect immediate valuation changes. Historical evidence and market mechanics show:

Market capitalization unchanged by the split itself: A stock split divides each share into multiple shares and reduces the per-share price proportionally; total market value is unchanged by the mechanical split alone.
Investor attention and liquidity: Stock splits can attract retail investor attention and may increase trading volume in the short term. Coverage around both the 2021 and 2024 splits noted heightened interest as the lower per‑share price often attracts additional retail participation.
Price movement drivers: Subsequent price movements following a split reflect standard market supply-and-demand dynamics, company fundamentals, macroeconomic conditions, and investor sentiment — not the split per se.

As of Dec 4, 2024, according to company announcements and contemporaneous market write-ups, trading began on a split-adjusted basis and providers adjusted historical prices. Media coverage emphasized that the split was a liquidity and accessibility measure, with market moves after the split attributed to broader market factors.

Cumulative split history and adjusted share counts

Arista’s split history (recent items):

Nov 18, 2021 — Four-for-one split completed.
Dec 3–4, 2024 — Second four-for-one split: charter amendment effective Dec 3, 2024 at 4:30 p.m. EST; trading split-adjusted from market open on Dec 4, 2024.

Cumulative effect:

Two consecutive 4-for-1 splits multiply to a 16-for-1 cumulative factor (4 × 4 = 16). That means one pre-2021 share is equivalent to sixteen post-2024 shares.

Adjusted shares and historical price series:

If you hold or analyze historical data, stock-price series from most financial-data vendors are adjusted for both splits so that historical per-share prices reflect the cumulative 16:1 factor. For example, to compare per-share prices across time you must divide pre-2021 nominal prices by 16 to place them on a post-2024 basis.

Comparison with peer companies

Stock splits are common among large-cap technology firms that wish to lower their per-share price while preserving shareholder value. When investors ask when did anet stock split, they often compare Arista’s split behavior to peers that have used splits to increase affordability and retail liquidity. Examples of typical rationale across peers include:

Making a share price more accessible to retail investors.
Expanding the potential investor base and facilitating more granular trading sizes.
Sending a signal of management confidence in long‑term prospects (though the split itself is not a performance guarantee).

Arista’s back-to-back 4-for-1 splits over a three-year window are consistent with other technology companies that adjust share counts as prices rise, balancing per‑share price with investor demand.

What investors and shareholders should know

If you are checking when did anet stock split because you hold ANET or track it, here are practical takeaways:

No action required in most cases: Brokers and transfer agents adjust holdings automatically for registered and street‑name holders.

Trading and custody tools: For traders and those who prefer integrated custody tools, consider Bitget for trading monitoring and Bitget Wallet for asset management features where applicable.

Q: When did anet stock split and does it affect dividends or voting?

A: The split itself changes the number of shares and adjusts per-share dividend and voting counts proportionally. Your total economic interest and voting percentage remain the same unless the company also issued new classes of shares or performed other recapitalizations at the same time.

A: Arista’s investor FAQ stated the split was intended to be a tax-free recapitalization for U.S. federal income tax purposes. Individual tax consequences can vary; seek professional tax advice.

Practical example: how splits affect per-share math

To understand the mechanics, consider a simplified example (hypothetical, round numbers for illustration): if a pre‑split share price were $160 and the company completed a 4-for-1 split, the post-split opening price would typically be about $40 per share (ignoring market movement). After two 4-for-1 splits (cumulative 16:1), a $160 pre-2021 price would be shown as $10 on a post-2024 adjusted basis for comparison. When doing historical return calculations or per-share metric analysis, always use split-adjusted price series to avoid misinterpretation.

Tracking split-adjusted data and resources

To reconcile holdings or perform historical analysis:

Use issuer filings and investor relations materials: Arista’s press releases and investor FAQ are the authoritative sources for split dates and mechanics.
Check transfer agent communications: For registered holders, the transfer agent provides statements and instructions.
